error: the trait `Foo` cannot be made into an object

--> $DIR/object-safety-err-where-bounds.rs:9:8

LL | fn test(&self) where [u8; bar::<Self>()]: Sized;

| ^^^^

= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
|
|
= note: for more information, see issue #51443 <https://github.com/rust-lang/rust/issues/51443>
|
|
note: for a trait to be "object safe" it needs to allow building a vtable to allow the call to be resolvable dynamically; for more information visit <https://doc.rust-lang.org/reference/items/traits.html#object-safety>
